Abstract

Five nucleotide sequence-specific deoxyribonucleases present in cell-free extracts of the filamentous cyanobacterium Nostoc PCC7524 have been purified and characterized. One of these enzymes, designated Nsp(7524)I cleaves at a new kind of nucleotide sequence i.e. 5'-PuCATG λ Py-3'. The other four restriction enzymes in this organism, designated Nsp(7524)II, Nsp(1524)III, Nsp(1524)IV and ... read more Nsp(1524)V, are isoschizomers of enzymes which have been previously described. The cleavage site of Nsp(1524)ll which is an isoschizomer of SduI was determined. show less
